Abstract
Purpose: To determine the value of computed tomography in assessment the stage of gingival cancer compared with pathology.
Methods: Aretrospective cross - sectional study included 102 patients with available CT-scans and pathology results of carcinoma of gingiva. This study compared the result of CT imaging and pathology to evaluate the diagnostic value of CT in assessing the stage and bone invasion of gingival cancer.
Results: During the period from August 2019 to July 2022 at the Ho Chi Minh city Oncology Hospital, 102 cases of gingival cancer were included in the study sample, of which 46 cases had tumor surgically removed.In measuring tumor size,CT measurements showed a strong correlation with macroscopic measurements with a Spearman correlation coefficient of 0.77. For the assessment of the two most common invasive sites, bone and retromolar trigone invasion, CT showed high diagnostic value with sensitivity of 97.6% and 88.8%, specificity of 71.4% and 91.7%, positive predictive value of 95.2% and 80.0%, negative predictive value of 83.3% and 95.7%, respectively. CT and pathological results showed good agreement in diagnosis of T stage, with weighted kappa index of 0.6 (95% CI, 0.4 - 0.9).
Conclusion: CT is the method of choice in staging gingival cancer. The CT assessment of gingival cancer should fully evaluate the factors to correctly evaluate
the disease stage according to 8th AJCC.
